But unlike the Mannings, Quinn is simply looking for a chance to compete this summer, taking second-team reps in practice along with Tim Tebow behind veteran Kyle Orton.
Quinn has languished in Tebow's shadow from the minute he landed in Denver, in a trade that sent running back Peyton Hillis to Cleveland.
Quinn even contemplated playing baseball during the NFL lockout, but his play this summer has turned some heads.
The Post reported that because teams aren't required to designate a No. 3 passer this season, Tebow might be used for "Tebow package" plays, with Quinn being viewed as a long-term answer at backup.
Quinn, the former Notre Dame star, saw mop-up time in Denver's first preseason game against the Dallas Cowboys on Aug. 11, throwing a pair of touchdowns. He'd like a chance to show what he can do with the team's starters.
"I feel like I can compete with anyone, given a fair chance," Quinn told The Post. "I mean, heck, throwing to (starting receiver) Brandon Lloyd every play? Give me that chance."
Quinn's teammates also have noticed an uptick in his confidence and performance.
